Respiratory syncytial virus (RSV) infection is the most common cause of hospitalization in infants and small children. The aim was to present a 13-months old boy diagnosed with acute airway infection, acute otitis media (AOM) and hepatitis during the RSV-infection.
Serum catalytic activities of alkaline phosphatase (ALP), aspartate aminotranspherase (AST), alanine aminotranspherase (ALT), gamma glutamyl transpherase (GGT), lactate dehydrogenase (LD), and concentrations of bilirubin were monitored during hospitalization and at control examination.
The child had clinical signs and symptoms of respiratory failure, AOM, and laboratory findings of virus infection and liver disease. On admission, catalytic activities of enzymes were markedly increased, especially the activity of ALP (10333 U/L, i.e. 24-fold increase in comparison with the upper reference limit). The highest increased in AST (339 U/L, 4.5-fold), ALT (475 U/L, 10.3-fold) and LD (545 U/L, 1.5-fold) were registered on the 3rd day, and the highest increase in GGT (68 U/L, 3.1-fold) occurred on the 11th day. Seven weeks after discharge AST, ALT, GGT and LD decreased into reference range, and ALP remain mildly increased (478 U/L, 1.1 fold increase). RSV was confirmed in nasal lavage fluid.
Laboratory results in patient with RSV infection needs to be interpreted in the light of both, respiratory and extrapulmonary manifestations of the infection, respectively.
呼吸道合胞病毒(RSV)感染是婴儿和幼儿住院的最常见原因。目的是介绍一名 13 个月大的男孩,在 RSV 感染期间被诊断出急性呼吸道感染、急性中耳炎(AOM)和肝炎。
在住院期间和对照检查时监测血清碱性磷酸酶(ALP)、天冬氨酸氨基转移酶(AST)、丙氨酸氨基转移酶(ALT)、γ-谷氨酰转移酶(GGT)、乳酸脱氢酶(LD)的催化活性和胆红素浓度。
患儿出现呼吸衰竭、AOM 的临床症状和体征,以及病毒感染和肝病的实验室发现。入院时,酶的催化活性明显增加,尤其是 ALP 的活性(10333 U/L,即与参考上限相比增加了 24 倍)。AST(339 U/L,4.5 倍)、ALT(475 U/L,10.3 倍)和 LD(545 U/L,1.5 倍)的最高增加发生在第 3 天,GGT(68 U/L,3.1 倍)的最高增加发生在第 11 天。出院后 7 周,AST、ALT、GGT 和 LD 降至参考范围,ALP 仍轻度升高(478 U/L,增加 1.1 倍)。在鼻洗液中证实了 RSV。
RSV 感染患者的实验室结果需要根据感染的呼吸道和肺外表现分别进行解释。
